Where to send Kodak Mailers ?

I have 6 that say "valid through 12/31/09". Are they now worthless? Also I have

some Fuji mailers and I was told these are honored at Dwayne's in KS?

Fuji Mailers:

Fujicolor Processing PO Box 837 Parsons, KS 67357

I believe Kodak K process is done there as well (and it is the only place in the US where it is done). This comes up in a search on P-net.

Here is the Kodak Addy.. which is the same:

Kodak Slide Processing, P. O. Box 1171, Parsons, KS 67357-1171

Both oof these were found by searching PNet Archives.

Just to be clear for anyone else stopping by this thread:

Dwayne's in Parsons Kansas is the current address for SLIDE mailers -

but Kodak PRINT mailers now go to their DALLAS address. There's a version of the Dallas address floating around that includes the street address, but I've also seen:

Kodak Mailer Processing

P.O. Box 36642

Dallas, TX 75235-9702

That address for sending prints to Kodak is exactly correct as I'm looking at the mailer's record stub right now. I will say, however, don't hold your breath waiting for the return package!

I recently ordered the mailers from Adorama (in New York, I believe). Could not find mailers, locally (Merced, CA).

I assume some of you have tried both the local store development (such as Longs, Rite Aid, etc) and the mail-in development. Can I get some opinion as to whether, or not, there is any significant difference in quality of prints?
